PCA

说明：  matlab工具箱，用于构建和重建可分离的正交可操纵金字塔。(a matlab toolbox for building and reconstructing separable quadrature steerable pyramids.)

可以动态调节运行环境的参数，重要参数的提取，利用自然梯度算法。( Can dynamically adjust the parameters of the operating environment, Extract important parameters, Use of natural gradient algorithm.)

使用双线性内插或二次曲面内插放大图像，然后使用彩色自蛇模型去除边缘模糊和锯齿效应(Using bilinear interpolation or quadratic surface interpolation to enlarge the image, then use the color removed from the snake model and the sawtooth effect of edge blur)

SAR SIM 仿真软件，可以参考看看，主要用于SAR雷达的成像仿真(SAR SIM simulation software, can refer to the SAR SIM simulation software, can refer to see)

@Wiener filter for Skull X-Ray images

背景音乐只是随便写了写,具体的可以改数组里的数字.有点闪的效果还是不太好看. (Background music just casually write write array of specific numbers can be changed. Bit flash effect is still quite nice.)

中值滤波，对3X3有优化，纯C，正对BMP格式(Median filtering, there are optimized for 3X3)

晨宇思远博客的代码------文件中代码实现小波图像融合，对低频和高频系数采用不同准则，有详细说明文件中代码实现小波图像融合，对低频和高频系数采用不同准则，有详细说明( morning yu siyuan blog code----------- file code implements wavelet image fusion, the low frequency and high frequency coefficient using different criteria, there are detailed description file code implements wavelet image fusion, the low frequency and high frequency coefficient using different criteria, there are elaborate)

一幅大小为256×256的256级灰度图像（每像素8bit） 如果图像的各个像素之间是统计独立的，求该图像的信息熵 -离散无记忆信源 如果图像的各个像素之间不是统计独立的，求该图像的信息熵 -图像像素的概率分布模型(A 256 gray scale image (8bit per pixel) with a size of 256 x 256 If each pixel of the image is statistically independent, the information entropy of the image is calculated Discrete memoryless source If each pixel of the image is not statistically independent, the information entropy of the image is calculated Probability distribution model of image pixels)

本文讲述了一种基于图像颜色直方图的图像相似度的度量的方法,。并用Matlab实现，有源代码(This article describes a method based on the image color histogram image similarity measure. And using Matlab, source code)
